GDPR laws are causing panic in Europe

Europe's sweeping data privacy law, the General Data Protection Regulation (GDPR), went into effect last Friday, triggering a flurry of multi-billion dollar complaints, the shuttering of news websites overseas and a programmatic (automated) ad-buying market crash in Europe.

Why it matters: There hasn't been any indication that enforcement will be that stringent — regulators have indicated they'll be more lenient in the beginning than businesses realize — but ominous press coverage and the fear of heavy penalties has been enough to rattle industry.

News outlets have gone dark in Europe: News publishers — many of which were linked to newspaper holding group Tronc, like The Chicago Tribune and The Los Angeles Times — shut down access to their websites from Europe on Friday. As of Monday, those sites were still reportedly blocked.

New paywalls are launching in Europe: The Washington Post, is reportedly adding an EU-specific paywall, that is ad and tracking-free, but is more expensive.

The tech giants are being slammed with complaints: Google and Facebook, the two biggest data-driven advertising companies globally, were hit with complaints filed by European privacy advocate Max Schrems just hours after GDPR went into effect. Potential penalties, Schrems argues, total up to € 7 billion.

Programmatic ad buying has plummeted: Since the early hours of May 25, ad exchanges have seen European ad demand volumes fall between 25 and 40% in some cases, sources tell Digiday. "Ad tech vendors scrambled to inform clients that they predict steep drops in demand coming through their platforms from Google."

The big picture: The panicked reaction to GDPR is significant because U.S.-based attempts to clean up the advertising industry have basically been ignored by marketers.

The Federal Trade Commission (FTC) has had native advertising guidelines around deception since 2015, but a lack of enforcement around the rules has caused many publishers to ignore them.
